HBOM Resources: Hardware & Firmware Trust
Visibility below the operating system: processors, firmware, embedded modules and their lifecycle, how to inventory them, validate supplier HBOMs and act on advisories.
Fundamentals
Guide · 7 minWhat is an HBOM? Hardware Bill of Materials explainedWhat a Hardware Bill of Materials (HBOM) contains, how CISA and CERT-In define it, which formats support it, and how to run HBOMs as a living inventory.Explainer · 3 minCycloneDX for hardware BOMs: device and firmware componentsHow to represent an HBOM in CycloneDX: device, firmware and device-driver types, nesting, identifiers, properties for CISA fields, and ECMA-424 status.Explainer · 3 minFirmware BOMs: bridging hardware and softwareWhat a firmware BOM is, why firmware needs one, how CycloneDX, SPDX, Redfish and uSWID represent it, and how NIST SP 800-193 and CNSA 2.0 shape firmware risk.Explainer · 3 minHardware supply-chain risks: counterfeits, tampering and firmware vulnerabilitiesHardware supply-chain risks explained: counterfeits, tampering, firmware flaws, restricted sources, availability and EOL, and the HBOM data for each.
Tools & platforms
Guide · 3 minHBOM platforms: evaluation criteria for hardware BOM managementHow to evaluate an HBOM platform: format support, supplier ingestion, field validation, firmware and EOL correlation, provenance, deployment and evidence.Guide · 4 minHBOM tools: open-source building blocks for hardware and firmware inventoryOpen-source HBOM tools compared: dmidecode, lshw, fwupd and LVFS, DMTF Redfish, CHIPSEC, uSWID and CycloneDX CLI, with what each can and cannot tell you.
Operations
Guide · 3 minHBOM generation: collecting hardware and firmware inventoryHow to generate an HBOM: combine supplier declarations, in-band and out-of-band collection, firmware data and identifiers into a CycloneDX or SPDX BOM.Guide · 3 minHBOM management: lifecycle, end-of-life and advisoriesHow to manage HBOMs over time: change control, end-of-life and end-of-support tracking, firmware advisories, VEX decisions and validation expiries.Explainer · 3 minHBOM validation: levels of assurance for hardware BOMsWhat HBOM validation means: schema validity, completeness, consistency with deployed hardware, firmware integrity and provenance, level by level.
